Opening a lot of tabs in Firefox can compress them so small that you don't know what each one is. This CSS tweak will enlarge the active tab, so you can at least always see what page you're working on.

If you miss the old title bar on Windows and need to see the title of the active page, this tweak is pretty handy. Just install the following userstyle with the Stylish extension (or add it to your userChrome.css file:

This will widen the active tab to 200 pixels, or whatever value you put under width. Mac users may not need this tweak as much, since they still have a titlebar that shows the active page's name. We've featured this tweak before, but it's changed, so here are the new values. This also excludes pinned tabs from the new width, so using pinned tabs will work as normal. While you're tweaking, too, you might as well set a custom tab width for all those inactive tabs with this tweak.
